The explanation this time is clearer, thanks.

I'm not sure where the misunderstanding lies. Here's how I understand this:
You say some kind of DRM is necessary in order to get a deal. Sure, that's
You say it's easier/safer to put all beam files in an archive and protect
it, as compared to protect each beam file. I may be wrong, but I think
there's no difference. If the code loader is extended so that it can load
from an encrypted archive, then it can just as easily load from separately
encrypted beam files. A cracker can do something about it if it cracks the
encryption, and in that case both alternatives are just as easy to tamper
with. Without the encryption key, a modified beam file would useless in both
What am I missing? What is a packaging into a smaller set of files adding to
the security level?
